Hello, VCO only affects the trace timestamps in the simulator. To simulate the clock, you can use a peripheral simulation model. An STM example can be found in the TRACE32 installation directory under demo\tricore\simulator\stm_aurix More information under simulator_api.pdf

Hello Khaled, Thank you for your reply. I'm looking at the demo\tricore\simulator\stm_aurix and the pdf file and i'm trying to understand how can I integrate this into my project. Should I replace my clock_init with SIMUL_Interface or SIMUL_Init? what do I use for processor? Its not clear how to use the example. Any clarification would be great.

Hello Ofer, The simulator API functions are not to be integrated into your application code (erikaOS). The peripheral simulation model is an additional software layer to be loaded into the TRACE32 instruction set simulator to mimic the behavior of a certain chip peripheral. For better understanding of the concept, please take a look at the "Overview" paragraph from simulator_api.pdf The demo script ~~\demo\tricore\simulator\stm_aurix\demo_stm_tc3xx.cmm shows how to load a simulation model for STM timers (see SIM.LOAD command). The source code of the simulation model is available in the src folder: ~~\demo\tricore\simulator\stm_aurix\src The model entry point is the function SIMUL_Init in stm_aurix.c

Thank you for your help. I got it working. How can I control the frequency of the ticks? Using: SIMUL_SetClockFrequency or SIMUL_SetClockCycle doesn't really change anything. All the best, Ofer.

Hello Ofer, In the provided example, the mode "SIMUL_TIMER_CLOCKS" is used. This means that the clock is increased with each step of the simulator. Then the VCO command is used to set the simulated clock. e.g. VCO.Frequency 300.MHz
